Everyone seems to have their favorite method for developing their film. I use the Jobo system for my 4x5 film because I have 3 reels and can develop up to 12 frames at one time. But loading film in the reels is a bit tedious and you have to be careful not to cross load in the slots. That is not a problem with BTZS tubes, loading them is super simple. One sheet of film rolled and slid into one tube. Cap it and you are loaded. I use the BTZS tubes for my 8x10 film and they certainly are convenient.
